Date to be displayed in two digits

I want the date to be displayed in two digits.

I have written a script to calculate yesterday's date. I'm getting the yesterday's date as 2009085.

Desired output:

20090805


Find the script below:

#!/bin/ksh
### Script to get Yesterday Date #############
Y=`date +'%Y'`
M=`date +'%m'`
D=`date +'%d'`
today=$Y$M$D
echo $today
if [ $M -eq 01 -o $M -eq 03 -o $M -eq 05 -o $M -eq 07 -o $M -eq 08 -o $M -eq 10 -o $M -eq 12 ] && [ $D -eq 01 ];then
yesterday=$Y$M`expr $D + 30`
echo $yesterday
else
if [ $M -eq 04 -o $M -eq 06 -o $M -eq 09 -o $M -eq 11 ] && [ $D -eq 01 ]; then
yesterday=$Y$M`expr $D + 29`
echo $yesterday
else
if [ $M -eq 02 -a $D -eq 01 ]; then
yesterday=$Y$M`expr $D + 27`
echo $yesterday
else
yesterday=$Y$M`expr $D - 1`
echo $yesterday
fi
fi
fi


Thanks

NAME
accounting - calculates statistics about your internet connections DESCRIPTION
accounting is a simple program to calculate statistics about your internet dial-up connections that are started and stopped by either ifup and ifdown or by a frontend to smpppd like cinternet , qinternet or kinternet. OPTIONS
These options are recognized by accounting. If a long option shows an argument as mandatory, then it is mandatory for the equivalent short option also. -l, --last=NUM Only consider the last NUM connections. -a, --after=DATE Only consider connections started after DATE. DATE is a date with optional time in ISO 8601 format, e.g. `2002-12-24 20:15:00'. Note that a date without time is treated as if the time is 00:00:00. Hence connections started on the specified date are consid- ered. -b, --before=DATE Only consider connections started before DATE. -u, --user=USER Only consider connections started by user USER. --this-year Only consider connections started this year. --last-year Only consider connections started last year. --this-month Only consider connections started this month. --last-month Only consider connections started last month. --this-week Only consider connections started this week. --last-week Only consider connections started last week. --today Only consider connections started today. --yesterday Only consider connections started yesterday. --per-year Show summaries on a per year basis. --per-month Show summaries on a per month basis. --per-week Show summaries on a per week basis. --per-day Show summaries on a per day basis. -c, --connections Only list the connections but do not show provider statistics. -p, --providers Do not list the connections only show the provider statistics. --connection-format=FORMAT The names of the columns to print in the connection list. The names must be separated by a comma. Known column names are time, type, provider, user, status, duration, rx, tx, rxtx, averx, avetx and averxtx. Each name may be appended by a colon and a number indicating the width for the column, e.g. provider:25. The value will not be truncated if the width is too small. --provider-format=FORMAT The names of the columns to print in the provider list equivalent to the --connection-format option. Known column names are provider, number, duration, rx, tx, rxtx, aveduration, averx, avetx and averxtx. --local Display all dates in local time. Also interpret dates on the command line in local time. This is the default. --utc Display all dates in UTC. Also interpret dates on the command line in UTC. --script[=STYLE] Format output for script. Known styles are c and sh. -f, --file=NAME Use a different file with accounting information. --report-errors Report erros in the accounting file. --version Show program version and exit. --help Show help information and exit. NOTES
All informations are only obtained through the accounting log. Hence the informations, esp. the data volume, of currently active connec- tions is not accurate. If you want the know the status of a connection, use ifstatus or a frontend to smpppd like cinternet , qinternet or kinternet instead. The user field is empty for connections started by a remote frontend of smpppd. BUGS
Not yet implemented for ISDN (ippp). FILES
/var/log/smpppd/accounting.log File containing accounting information. SEE ALSO
kinternet, qinternet, cinternet(1), smpppd(8), smpppd-ifcfg(8). AUTHOR
